380 million location data from 137 countries: a previously unknown data set from a US data broker shows the dangers of global data trading. 40,000 apps are affected, including queer dating apps. For some apps, the shared location data is very precise.
I interviewed a bunch of years ago with a company called “xmode social” (I was in desperate need of a job. I fortunately did not get that one.) They had a framework that they paid app publishers in to include in their apps. That framework collected your location data and sent it to xmode who sold that data. That was their entire business AFAIK.
There don’t need to be any shared features for companies to include shit like that in their apps. They just need a way to make the line go up.
